- the method of WO 2010/0177133 is applicable to preparing the present polymers using NDCA or DMN or other C 2 to C 10 alkyl diesters of NDCA.
- the polymers of the present invention may be made by a two-step process, wherein first, in Step (I), a prepolymer is made having 2,6-napthalene
- This intermediate product is preferably an ester composed of two diol monomers and one diacid monomer, wherein the diacid monomers comprise NDCA, followed by a melt-polymerization of the prepolymers under suitable polymerization conditions. Such conditions typically involve reduced pressure to remove the excess of diol monomers.
- DMN is reacted in a catalyzed transesterification process with about 2 equivalents of a diol, to generate the prepolymer while removing 2 equivalents of the corresponding alcohol.
- DMN is preferred, since this transesterification step then generates methanol, a volatile alcohol that is easy to remove.
- diesters of NDCA with other volatile alcohols or phenols may be used as well.
- examples include ethanol, methanol and a mixture of ethanol and methanol.
- the reaction leads to formation of a polyester.
- the diol monomers may contain additional hydroxyl groups, such as glycerol, pentaerythritol or sugar alcohols.
- Step (I) is commonly referred to as esterification when acid is used, and transesterification when ester is used, with concomitant removal of water or an alcohol, respectively.
- Step (II) of the process is a catalyzed polycondensation step, wherein the prepolymer is polycondensed under reduced pressure, at an elevated temperature and in the presence of a suitable catalyst.
- the first step, transesterification is catalyzed by a specific transesterification catalyst at a temperature preferably in the range of about 150 to about 220°C, more preferably in the range of about 180 to about 200°C, and carried out until the starting ester content is reduced until it reaches the range of about 3 mole to about 1 mole .
- the transesterification catalyst may be removed, to avoid interaction in the second step of polycondensation, but often remains present for the second step.
- the selection of the transesterification catalyst can be affected by the selection of the catalyst used in the polycondensation step, and vice versa.
- Suitable catalysts for use in the Step (I) transesterification process include tin(IV) based catalysts, preferably organotin(IV) based catalysts, more preferably alkyltin(IV) salts including monoalkyltin(IV) salts, dialkyl and trialkyltin(IV) salts and mixtures thereof.
- the tin(IV) based catalysts are better than tin(II) based catalysts, such as tin(II) octoate.
- the tin(IV) based catalysts may also be used with alternative or additional transesterification catalysts.

- Preferred transesterification catalysts are selected from one or more of, butyltin(IV) tris(octoate), dibutyltin(IV) di(octoate), dibutyltin(IV) diacetate, dibutyltin(IV) laureate, bis(dibutylchlorotin(IV)) oxide, dibutyltin dichloride, tributyltin(IV) benzoate and dibutyltin oxide.
- the active catalyst as present during the reaction may be different from the catalyst as added to the reaction mixture.
- the catalysts are used in an amount of about 0.01 to about 0.2 mole relative to initial diester, more preferably in an amount of about 0.04 to about 0.16 mole of initial diester.
- the intermediate product i.e., the prepolymer
- the product is used as such in the subsequent polycondensation step.
- the prepolymer is polycondensed under reduced pressure, at an elevated temperature and in the presence of a suitable catalyst.
- the temperature is preferably in the range of about the melting point of the polymer to about 30°C above this melting point, but preferably not less than about 180°C.
- the pressure should be reduced, preferably gradually at stages. It should preferably be reduced to as low as a pressure as possible, more preferably below 1 mbar.
- Step (II) is catalyzed by specific polycondensation catalysts and the reaction is carried out at mild melt conditions.
- suitable polycondensation catalysts for use in Step (II) include tin(II) salts, such as tin(II) oxide, tin(II) dioctoate, butyltin(II) octoate, or tin(II) oxalate.
- Preferred catalysts are tin(II) salts obtained by the reduction of the tin(IV) catalyst, e.g., alkyltin(IV), dialkyltin(IV), or trialkyltin(IV) salts, used as transesterification catalyst in Step (I), with a reducing compound.
- Reducing compounds used may be well-known reducing compounds, preferably phosphorus compounds.
- Particularly preferred reducing compounds are organophosphorus compounds of trivalent phosphorus, in particular a monoalkyl or dialkyl phosphinate, a phosphonite or a phosphite.
- suitable phosphorus compounds are triphenyl phosphite, diphenyl alkyl phosphite, phenyl dialkyl phosphite, tris(nonylphenyl) phosphite, trilauryl phosphite, trioctadecyl phosphite, distearyl pentaerythritol diphosphite, tris(2,4-di-tert-butylphenyl) phosphite, diisodecyl pentaerythritol diphosphite, di(2,4-di-tert-butylphenyl) pentaerythritol diphosphite, tristearylsorbitol triphosphit
- the preferred polycondensation catalysts therefore include tin(II) salts such as tin(II) dioctoate, butyl(II) octoate and other alkyltin(II) octoate compounds, prepared from the corresponding tin(IV) salt using e.g., a trialkyl phosphite, a monoalkyl diaryl phosphite, a dialkyl monoaryl phosphite or a triaryl phosphite.
- the reducing compound is added in the melt of the prepolymer. Addition of the reducing compound at that stage avoids discoloration.
- a combination of transesterification catalyst and polycondensation catalyst that may be particularly suitable is based on a tin(IV) type catalyst during transesterification, which is reduced, preferably with triphenylphosphite and/or tris(nonylphenyl)phosphite, to a tin(II) type catalyst during the polycondensation.
- the catalysts are used in an amount of about 0.01 to about 0.2 mole % relative to initial diester, more preferably in an amount of about 0.04 to about 0.16 mole of initial diester.
- tin(IV) type catalyst retains activity. This allows for the same catalyst to be used for a subsequent solid state polycondensation.
- Solid state polycondensation is a common process used in the preparation of other polyesters, such as PET.
- SSP processes pellets, granules, chips or flakes of polymer are subjected for a certain amount of time to elevated temperatures (below melting point) in a hopper, a tumbling drier or a vertical tube reactor or the like.
- elevated temperatures below melting point
- Tin type catalysts allow SSP of the NDCA-based polymers to reach a number average molecular weight of 20,000 and greater. Conditions and equipment for SSP are known, in particular as SSP is frequently used to upgrade recycled PET. In applying the SSP process to these polymer systems, the temperature should be elevated relative to traditional SSP processes (as for PET), but nonetheless remain below, and preferably well below, the melting point of the polymer.
- Polyesters and various copolymers may be made according to the process described above, depending on the selection of the monomers used. Furthermore, the copolymers may be formed as random or block copolymers depending on the process and process conditions employed. For instance, linear polyesters may be made with NDCA (in the form of its methyl ester) and isosorbide and an aromatic, aliphatic or cyclo aliphatic diol. The Q to Cio alkyl diester of NDCA may be used in combination with one or more other dicarboxylic acid esters or lactones. Likewise, the diol may be a combination of two or more diols.
- Polyesters that have never been produced before and that are claimed in this application are those having both a 2,6-napthalene dicarboxylate moiety and isosorbide within the polymer backbone.
- the polyesters will comprise residues of other diacid(s) and/or diester(s), and may comprise residues of other polyols as well.
- the polymers and copolymers according to the current invention need not be linear. If a polyfunctional aromatic, aliphatic or cycloaliphatic alcohol is used, or part of the diol is replaced by such a polyol, then a branched or even crosslinked polymer may be obtained. A branched or crosslinked polymer may also be obtained when part of the NDCA ester is replaced by an ester of a polyacid. However, branching would reduce barrier properties, and too much crosslinking would impair film processability. As a result, the polymers should have only a moderate degree of branching or crosslinking, or little to essentially no branching or crosslinking, and preferably have no branching or crosslinking.

- lactones examples include pivalolactone, ⁇ -caprolactone and lactides (L,L; D,D; D,L) and glycolide.
- the polymers and copolymers according to the current invention need not be linear. If a polyfunctional aromatic, aliphatic or cycloaliphatic alcohol is used, or part of the dihydroxyl polyol is replaced by a tri- or higher OH-functional polyol, then a branched or even crosslinked polymer may be obtained. A branched or crosslinked polymer may also be obtained when part of the DMN is replaced by an ester of a polyacid. Nevertheless, linear polymer and copolymer are preferred.
